Projection System Generating 3D Images

Abstract

A projection system generating 3D images comprises: an illumination system, a display panel having two separate regions displaying images for right eye and left eye respectively; a projection lens system that comprising a deflecting unit that deflects the images of left eye and right eye at different angles; and a polarization modulator that modulates the images of different eyes at different polarization states. The viewer wears a piece of passive polarization glasses to see the 3D images. The advantages of present invention are: simple structure and low cost. It produces 3D images by single display panel.

1 . A system generating 3D images comprises:
 a) at least one display panel having two separate regions displaying images for right eye and left eye respectively;   b) a deflecting unit that can deflect the images for left eye and right eye at different angles to converge them to a 3D image on the screen or human's eyes.   c) a polarization modulator that give the images of different eyes different polarization states;   d) and a projection lens system.   
     
     
         2 . The system generating 3D image as specified in  claim 1  wherein said display panel displays different color at different time to generate full color 3D images. 
     
     
         3 . The system generating 3D image as specified in  claim 1  wherein said display panels comprises red green and blue display panels wherein the right region and left region of each panel display different images for right eye and left eye; and a color combination unit that merge three different color image into a full color 3D image. 
     
     
         4 . The system generating 3D image as specified in  claim 1  wherein said deflecting units are two reflecting mirror, said mirrors are placed at the location where the light from left region and right region of said display panels are fully separated. 
     
     
         5 . The system generating 3D image as specified in  claim 1  wherein the right and left regions of said display panels generate lights at different polarization states. 
     
     
         6 . The system generating 3D image as specified in  claim 1  wherein the right and left regions of said display panels generate the lights at the same polarization states; and further comprises a polarization modulating component at the location where the lights from right and left portion of the panels are fully separated. 
     
     
         7 . The system generating 3D image as specified in  claim 1  further comprises a electronic image processing system, said electronic image processing system further comprises: 1) input unit receiving digital or analog 3D signal; 2) a unit separating the signals for right eye and left eye; 3) a unit correcting the distortion of the images for right eye and left eye; and a unit sending said different signals to different region of said display panels. 
     
     
         8 . The system generating 3D image as specified in  claim 1  said display panels are two separate panels displaying images for right eye and left eye; said display panels are placed substantially on a same plane and close to each other. 
     
     
         9 . The system generating 3D image as specified in  claim 1  further comprises a polarization glasses. 
     
     
         10 . The system generating 3D image as specified in  claim 1  said polarization modulator applies different polarization states onto the light from right region and left region of said display panels.
